Google has begun testing a “Buy” button that lets shoppers in India purchase products from Walmart-owned Flipkart directly within its Gemini assistant and AI Mode, marking a notable shift from using artificial intelligence to recommend products toward enabling transactions inside the search experience. The integration, which surfaced in an early test seen by this publication, represents the search giant’s most concrete step yet toward closing the loop between AI-driven shopping queries and actual purchases — and it arrives just ahead of India’s festive season, when e-commerce spending peaks.
What the Flipkart Buy Button Looks Like Inside Gemini and AI Mode
Users enrolled in the test see a “Buy” button on select Flipkart product listings that appear in Gemini answers and in Google’s AI Mode, a separate interface designed for conversational search. Tapping the button triggers a checkout flow that remains branded under Flipkart, not Google. The experience does not require the user to leave the AI interface; instead, a Flipkart-hosted payment and shipping screen loads in a panel or new window, depending on the device and browser context.
The question is not whether AI will become a shopping medium, but which companies will control the checkout button when it does.
The test is limited to a small subset of users and a narrow catalog of products — primarily smartphones, electronics, and mobile accessories. This suggests Google and Flipkart are proceeding cautiously, likely monitoring conversion rates and user experience friction before expanding the offering. Other users who ask Gemini for shopping advice still see standard Flipkart product links and cards but no direct purchase option.
Google plans to roll the feature out more broadly later in October, according to a person familiar with the company’s internal plans. The timing is deliberate: India’s festive shopping season, which includes Diwali and other major sales events, typically sees tens of millions of transactions across Flipkart and Amazon, and both platforms invest heavily in marketing and discounts.
Google and Flipkart’s Deepening Ties Go Beyond Technology
The test is not occurring in a vacuum. Google invested approximately $350 million in Flipkart in 2024 as part of a funding round led by Walmart, the e-commerce company’s majority owner. That investment gave Google a minority stake and formalized a strategic partnership that now appears to be bearing fruit in the AI commerce arena. Earlier this month, Google publicly named Flipkart as one of the merchants partnering with it to bring what it calls “agentic” shopping experiences to Indian consumers, though it did not disclose the specifics of the Buy button test or its rollout timeline at the time.
For Flipkart, the integration provides a privileged channel into Google’s AI surfaces — one that its chief rival Amazon in India does not yet have. In the test observed, product listings from Amazon appeared alongside Flipkart’s in Gemini and AI Mode, but Amazon’s listings lacked the Buy button. That asymmetry could tilt the competitive dynamics during the festive season if the rollout reaches a large enough audience.
The Broader Push: From Product Discovery to Transactional AI
Google’s move mirrors a wider industry trend. OpenAI, for instance, recently began testing a feature that allows ChatGPT users to shop directly from Walmart. The underlying goal for all major AI platform builders is the same: move beyond answering queries and steering users toward retailer sites, and instead become a genuine commerce intermediary that captures transaction data and, potentially, referral fees or commissions.
Behind the scenes, Google has been constructing the technical plumbing for exactly this kind of integration for years. In January 2026, the company introduced the Universal Commerce Protocol (UCP), an open standard designed to let AI agents handle the entire shopping journey — from product discovery to checkout — by communicating directly with retailer systems. At the time, Google said the protocol would allow shoppers to buy eligible products through Gemini and AI Mode using a Google-hosted checkout experience. The company later expanded UCP to include the option for shoppers to transfer items to the retailer’s own site to complete the purchase.
The Flipkart test appears to diverge from the Google-hosted checkout model. When a user taps the Buy button, the checkout flow that appears is clearly Flipkart-branded, not Google-branded. It remains unclear whether the test uses UCP, a custom API, or another integration method. A Google spokesperson declined to provide technical details, saying only that the company is “always testing new features and experiences to help people discover and connect with businesses more easily” and that it has no further information to share beyond describing the test as a routine experiment.
How Does Google’s Flipkart Buy Button Work in Gemini?
The Buy button appears on select Flipkart product listings within Gemini answers and AI Mode. When clicked, it initiates a Flipkart checkout flow without the user leaving the AI interface. The flow handles payment, shipping address, and order confirmation through Flipkart’s own system. The test is currently limited to a small group of users and a limited set of product categories, including smartphones, electronics, and mobile accessories. Google expects to expand the feature to more users in October, just before India’s festive shopping season.
Why India? Market Dynamics and Strategic Rationale
India is the world’s second-largest internet market, with more than one billion internet subscribers. E-commerce penetration remains relatively low compared to mature markets, but growth is rapid, and competition between Flipkart and Amazon is ferocious. Both companies pour billions into logistics, advertising, and exclusive partnerships to capture share. The festive season represents the high-stakes battleground: each company’s biggest sales events occur during this period, and the volume of transactions can determine annual rankings.
For Google, adding a direct purchase capability is not just a feature for convenience — it is a strategic hedge. If AI assistants become the primary way consumers discover and evaluate products, the companies that control that interface will hold enormous influence over which retailers win or lose. By integrating with Flipkart first, Google aligns itself with a key strategic partner in which it already has a financial stake. It also sends a signal to other Indian retailers and to Amazon itself that access to the most frictionless purchase path in AI Mode may require deeper commercial relationships.
The Competitive Landscape and What It Means for Amazon
Amazon has long been a major advertiser on Google’s search platform, but the Flipkart test redefines the terms of engagement. If Google’s AI surfaces become a transactional channel exclusive or heavily tilted toward Flipkart, Amazon could face a structural disadvantage in the crucial festive season. Amazon’s own AI efforts include Alexa Shopping and experimental integrations with third-party assistants, but it does not yet have the equivalent of a Buy button inside the search engine that handles more than 90 percent of Indian queries.
The test also raises questions about how Google will handle parity. Will it eventually offer Amazon a similar integration, or will it demand reciprocal investment, data sharing, or advertising commitments? Google has historically maintained that its AI features aim to surface the best results regardless of commercial relationships, but the Flipkart Buy button represents a clear exception — it gives one retailer a transactional advantage that others, for now, do not have.
Technical Underpinnings and the Role of the Universal Commerce Protocol
Although Google has not confirmed the technology stack behind the Flipkart test, the existence of the Universal Commerce Protocol suggests a possible foundation. UCP is described as an open standard for AI agent–retailer communication across the full shopping journey, including inventory checks, price comparisons, and checkout. If the Flipkart integration uses UCP, it would mean Google and Flipkart have implemented the standard in a way that allows the AI to hand off to Flipkart’s own checkout rather than Google’s hosted version.
Alternatively, the integration could rely on a simpler API connection or even a deep-link scheme that passes product identifiers and session tokens between Gemini and Flipkart’s servers. The fact that the checkout remains Flipkart-branded suggests Google is comfortable letting the retailer own the payment experience, likely because it reduces Google’s regulatory and liability exposure in a market where e-commerce payment regulations are complex.
What Comes Next for AI Shopping in India and Beyond
The limited October rollout is intended to test performance under real festive-season conditions. If the conversion rates, user satisfaction, and merchant feedback are positive, Google could expand the Buy button to more product categories and, eventually, to more retailers. The company has previously stated that UCP will eventually allow any retailer to participate, provided they meet the protocol’s requirements. That vision, if realized, would transform Google from a search engine into a commerce platform where AI handles the entire buying process — a model that has eluded the company since the early days of Google Shopping.
For consumers, the benefit is convenience: the ability to ask a question in natural language, see a recommended product, and buy it in a few taps without switching contexts. For retailers, the cost of admission may be a willingness to integrate deeply with Google’s AI infrastructure and, likely, a revenue-sharing arrangement. For Google, the prize is data — on purchase intent, conversion behavior, and user preferences — that is far more valuable than click-through rates and ad impressions.
India is the opening act. If the Flipkart test succeeds, similar integrations with major retailers in other markets — from the United States to Southeast Asia — are likely to follow. The question is not whether AI will become a shopping medium, but which companies will control the checkout button when it does.
